A mother in Denton County, Texas, has been arrested after she allegedly forced her way onto a school bus Tuesday and hit and kicked some of the children on board.

The woman accused of the assault, Alexandria Harris, 32, of Little Elm, was arrested on three counts of injury to a child.

Police said the incident happened on the 2600 bock of Harbor Lights Drive near Harris' home.

"She was really mad. She was, like, really angry," said Austin Muller, a sixth-grade student at Little Elm Middle School who was on the bus when the incident happened.

Muller, 11, spoke to NBC 5 about what happened with his parents' permission.

He said the bus driver tried to close the door as she approached, but she used her hands to pry open the door.

"The bus driver was yelling at her, 'Get off my bus right now,'" Muller said.

The school bus driver called police after the woman boarded the bus while at a stop, according to a news release from the Little Elm Independent School District.

She asked for certain children by name and was cussing, Muller said.

"She was trying to find these three kids," Muller said. "She was trying to defend her daughter, I'm guessing, because everybody was picking on her daughter and I guess she just wanted to get them back."

Muller said he heard that some students were teasing the woman's daughter, but had not witnessed it.

"And she was like pushing kids over," he said. "This one kid fell over on the aisle."

Harris said students were startled. "Everybody got scared," he said.

Some students ran for cover in the back of the bus, he said.

"She hit a lot, like a whole lot," Harris said. "Like the kid who was standing next to me in the alley, he got hit and kicked in the leg."

Police said the students, an 11-year-old boy, 12-year-old boy and an 11-year-old girl, suffered minor injuries in the attack but did not need medical treatment.

The district and police noted that allegations and speculation of bullying had been circulating on social media. In response to that, the district said they take the safety of all students seriously and work daily to insure the children are learning in a secure environment.

“We are in full cooperation with the Little Elm Police Department,” said Lynne Leuthard, superintendent of schools. “I encourage anyone with information surrounding this situation to contact the police immediately.”

Harris remained in the Denton County jail Wednesday evening on $30,000 bond. She has no known criminal history.
